C2ME 0.3.0 for Minecraft 1.21.3 is released
Key highlights:
- Partially rewrites the chunk system. This release introduces a dead simple implementation of the scheduling subsystem designed to perform reliably under high load. It eliminates the need of complex workarounds caused by design pitfalls of the vanilla chunk system.
- Introduces the density function compiler. This new optimization accelerates world generation datapacks by up to 30% by compiling them into JVM bytecode, avoiding all kinds of overhead caused by interface method calls.
